Restrictions on non-Clifford fault tolerance and ruling out beyond-SQL quantum metrology

Constantin Cedillo Vayson de Pradenne, Ishaan Kannan, Harald Putterman +1

The paper proves limits on transversal non‑Clifford gates in stabilizer codes, showing these constraints prevent fault‑tolerant transversal sensing that would surpass the standard…

Learning Hamiltonians at Long Times

Constantin Cedillo Vayson de Pradenne, Jordan Cotler, Hsin-Yuan Huang

We study the problem of learning an unknown $n$ -qubit Hamiltonian $H$ from $U = e^{- i H t}$ for a single time $t$ , where $t$ may be arbitrarily large. For broad families of local Ham…
